摘要
Oracle数据库系统是目前世界的主流数据库,是一种集业务量大、存储量大、极其灵活等特点的关系型数据库。它可以运行在多种硬件平台和操作系统上,在我国工商业、军事、航空等诸多领域发挥积极作用。它承担着业务数据的存储和处理任务,对于整个应用系统极为重要。数据库系统的可靠性和可用性是首要的需求,为确保数据库系统持续稳定高效的运行,必须保证较高的可靠性、稳定性。由于计算机出现的安全问题(如设备故障、操作系统故障、网络通信中断、病毒攻击、木马、间谍软件、可疑代码、端口扫描、DoS/DDo等),这些异常的数据库操作都会造成数据的不完整和数据丢失。所以需要建立相应的备份和容灾机制,对数据的集中管控、容灾与保护。本文探讨Oracle数据库的备份与恢复相关技术,并给出了相应的解决方案。
At present, the world mainstream database is Oracle database system, which is a kind of relation type database and extremely flexible. Meanwhile, it also has a large volume of business, large storage capacity. It is used in a variety of hardware platform and operating systems;therefore, it plays a positive role in China＆#39;s industrial and commercial, military, aviation and many other fields. Also it undertakes the task of business data storage and processing, which is very important to the whole application system. As we know, the reliability and availability of database systems is the primary demand, to ensure that the database system is stable and efficient operation, we must guarantee the reliability, high stability. Because the computer security problems arise （such as equipment failure, operating system failure, network communication interrupt, virus attack, Trojan virus, spy ware, suspicious code, port scanning, DoS/DDo）, the abnormal operation of the database will cause the incompleteness of data and data loss. As a result, It is necessary to build the corresponding backup and disaster recovery mechanism to conduct centralized management, disaster recovery and protect data. This paper discusses the Oracle database backup and recovery technology, and gives the corresponding solutions.
